Exoplanets with substantial hydrogen/helium atmospheres have been discovered in
abundance, many residing extremely close to their parent stars. The extreme irradiation …

How has the solar wind evolved to reach what it is today? In this review, I discuss the long-
term evolution of the solar wind, including the evolution of observed properties that are …

A new piece of evidence supporting the photoevaporation-driven evolution model for low-
mass, close-in exoplanets was recently presented by the California–Kepler Survey. The …

The composition of a planet's atmosphere is determined by its formation, evolution, and
present-day insolation. A planet's spectrum therefore may hold clues on its origins. We …

Inspired by the Kepler mission's planet discoveries, we consider the thermal contraction of
planets close to their parent star, under the influence of evaporation. The mass-loss rates …

The mass–period or radius–period distribution of close-in exoplanets shows a paucity of
intermediate mass/size (sub-Jovian) planets with periods≲ 3 d. We show that this sub …

We use an end-to-end model of planet formation, thermodynamic evolution, and
atmospheric escape to investigate how the statistical imprints of evaporation depend on the …

We use models of coupled thermal evolution and photo-evaporative mass loss to
understand the formation and evolution of the Kepler-36 system. We show that the large …

The radius distribution of small, close-in exoplanets has recently been shown to be bimodal.
The photoevaporation model predicted this bimodality. In the photoevaporation scenario …

The extreme ultraviolet (EUV)/X-ray photoevaporation and core-powered mass-loss models
are both capable of reproducing the bimodality in the sizes of small, close-in exoplanets …
